PAPILIONACEOUS FLOWERS. 
466. These are so called from a Latin word papilio, a butter- 
fly, on account of the supposed resemblance between them and 
that insect; they are generally flowers with brilliant colouring, 
and of a showy appearance. The sweet-pea may be given as

a highly fragrant perfume.

Rose, the Pink, and the Bell-flower, are regular in their form, 
that is, there is a symmetry and equality in their parts. Irre-
